  • Torngat Mountains National Park
    TORNGAT MOUNTAINS NATIONAL PARK Presentation to Special Senate Committee on the Arctic November 19, 20018 1 PURPOSE Overview of the Torngat Mountains National Park Key elements include: • Indigenous partners and key commitments; • Cooperative Management structure; • Base Camp and Research Station overview & accomplishments; and • Next steps. 2 GEOGRAPHICAL CONTEXT 3 INDIGENOUS PARTNERS • Inuit from Northern Labrador represented by Nunatsiavut Government • Inuit from Nunavik (northern Quebec) represented by Makivik Corporation 4 Cooperative Management What is it? Cooperative management is a model that involves Indigenous peoples in the planning and management of national parks without limiting the authority of the Minister under the Canada National Parks Act. What is the objective? To respect the rights and knowledge systems of Indigenous peoples by incorporating Indigenous history and cultures into management practices. How is it done? The creation of an incorporated Cooperative Management Board establishes a structure and process for Parks Canada and Indigenous peoples to regularly and meaningfully engage with each other as partners. 5 TORNGAT MOUNTAINS NATIONAL PARK CO-OPERATIVE MANAGEMENT BOARD 6 BASECAMP 7 EVOLUTION OF BASE CAMP 8 VALUE OF A BASE CAMP 9 10 ACCOMPLISHMENTS An emerging destination Tourism was a foreign concept before the park. It is now a destination in its own right. Cruise ships and sailing vessels are also finding their way here. Reconciliation in action Parks Canada has been working with Inuit to develop visitor experiences that will connect people to the park as an Inuit homeland. All of these experiences involve the participation of Inuit and help tell the story to the rest of the world in a culturally appropriate way.

    The Glaciers of the Torngat Mountains of Northern Labrador By © Robert Way A Thesis submitted to the School of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science Department of Geography Memorial University of Newfoundland September 2013 St. John 's Newfoundland and Labrador Abstract The glaciers of the Tomgat Mountains of northem Labrador are the southemmost m the eastern Canadian Arctic and the most eastem glaciers in continental North America. This thesis presents the first complete inventory of the glaciers of the Tomgat Mountains and also the first comprehensive change assessment for Tomgat glaciers over any time period. In total, 195 ice masses are mapped with 105 of these showing clear signs of active glacier flow. Analysis of glaciers and ice masses reveal strong influences of local topographic setting on their preservation at low elevations; often well below the regional glaciation level. Coastal proximity and latitude are found to exert the strongest control on the distribution of glaciers in the Tomgat Mountains. Historical glacier changes are investigated using paleomargins demarking fanner ice positions during the Little Ice Age. Glacier area for 165 Torngat glaciers at the Little Ice Age is mapped using prominent moraines identified in the forelands of most glaciers. Overall glacier change of 53% since the Little Ice Age is dete1mined by comparing fanner ice margins to 2005 ice margins across the entire Torngat Mountains. Field verification and dating of Little Ice Age ice positions uses lichenometry with Rhizocarpon section lichens as the target subgenus. The relative timing of Little Ice Age maximum extent is calculated using lichens measured on moraine surfaces in combination with a locally established lichen growth curve from direct measurements of lichen growth over a - 30 year period.
